Virtual Ron Posted November 13, 2011 Share Posted November 13, 2011 I have a WD Ext HDD 1021 USB connected, 3 Terabyte Hard drive. After a little time, Defraggler will sense that it is connected (though not usually immediately, as for hard drives. Any time that I try to analyze the drive for fragmentation, Defraggler returns the message "Analysis failed". I am using the latest version of Defraggler. I am running Windows XP, not Windows 7.

eL_PuSHeR Posted November 14, 2011 Share Posted November 14, 2011 This has been discussed earlier. It seems DF has some problems with drives bigger than 1,5 TB + Link to comment Share on other sites More sharing options...
Virtual Ron Posted November 19, 2011 Author Share Posted November 19, 2011 Thanks for the head's-up. Is there any indication that this is being addressed? It would seem likely that dirves are not going to be getting any smaller... Ah-- strike that question-- found it in another thread and forum: yes, apparently the issue is being "looked into". Good t hear. Link to comment Share on other sites More sharing options...
JonathanPDX Posted December 19, 2011 Share Posted December 19, 2011 Ah...I was wondering why it kept failing. Well, I guess I'll fall back to MyDefrag till the problem is resolved. I was really looking forward to using Defraggler. I have 2 of the 3TB WD Drives and it would have worked really well schedule-wise. Thanks for the heads-up!

I was really looking forward to using Defraggler. I have 2 of the 3TB WD Drives and it would have worked really well schedule-wise. Thanks for the heads-up! I used to use MyDefrag instead of Defraggler, but now I use more Defraggler than MyDefrag. MyDefrag is slower and crashes more easily, but it might do a bit "better" work than Defraggler. Defraggler can be used also as portable, which is good. Also MyDefrag haven't been updated in a while; v4.3.1 came ~1,5 years ago. Link to comment Share on other sites More sharing options...
jcall Posted May 3, 2012 Share Posted May 3, 2012 To whom it may concern, I am running a Vista box and a Win7 box each with a WD My Book Essentials 3TB Ext HDD (WDBACW0030HBK-NESN) that also show ''Analysis Failed''. I also own the same but in 2TB drives (WDBACW0020HBK-NESN) that analyze and defrag just fine. I frequently use quick defrag: df X: /QD For the 3TB drives, I use the OS defrag: %windir%\system32\defrag.exe X: until Piriform.com gets this issue fixed. I hope it will be soon. I'm migrating to 4TB and 8TB drives soon. Thank you for your time. John Callaghan, Eng. Link to comment Share on other sites More sharing options...
